That's generally what happens, and I think it's healthy, too. There's just only so long one can maintain this level, I think (unless your janton, but he's not even on the list anywhere so who knows who great he's still doing. :).
So, as we slip away, there are others to take our place, and we theirs when we come back for round two. :)
Good luck with your busy schedule ahead. Hopefully there will be things you want to do.
